SPECIFICATION forming part of Letters Patent No. 526,849, dated October2, 1894. Application tiled November 2, 1 893. Serial No. 489,866. (Nomodel.)

To all whom t mayconcern:

Be it known that I, ABRAHAM S. ADLER, a

, citizen of the United States, residing atI Baltimore, in the State ofMaryland, have invented certain new and useful Improvements inConformators; and I do hereby declare the following to be a full, clear,and exactdescription of the inve ntion,such as will enable othersskilled in the art to which it appert'ains to make and use the same. p

Figure 1, represents a perspective view jof a conformator embodying myinvention. Fig.'

2, is a transverse section al viewon vthe line 2 2 of Fig. 1. Fig. 3, is'a lside elevation showing the inserted last partially rotated. Fig. 4,is a detail showing one of the rotating disks with its pivoted carryinglever and supporting arm detached from the machine. Fig. 5, representsone of the disks with its face plate provided with a lug or stop andshowing a portion of said plate broken awayy to disclose the spiralspring.

My present invention relates to certain new and usefulv conformatorsadapted especially? for last-makers use. It is an improvement on myformer patent, No. 506,761, dated yOctober 17, 1893, and issued to mejointly with another,'and it consists of the constructions,V

arrangements and combinations of parts which I shall hereinafter fullydescribe and claim. j

Referring now to the drawings for amore complete explanation of myinvention, A represents a frame of suitable design and construction andcomprising a base a and end standards b and b.

The end standards b and b of the machine are formed or provided withbearings for the end journals of parallel rods B and C, one of which Bhas a series of lines or marks representing different lengths of lasts,while the rod C is formed or provided with threads of varying sizes fora purpose I will hereinafter fully disclose. Y

The standardb at one end of the machine is provided near its upper endwith a bearing din which a horizontal pin or rod eis' adjustablymounted. This pin or rod has a groove or key-way f engaged by a featheror pin g in the bearing, whereby the pin or rod and to be held in an adjusted position in and outby means of a set screw h engaging it as shown.

The inner end of the pin or rod is formed to represent the toemeasurement of a given last.

The rod e in connection with a pin or rod e at the heel portion of themachine constitutes the suspending devices between which the last ishung; and said pin or rod e is mounted to turn in a bearing l in theupper end of a standard D, o'r equivalent device secured to its outerend.

On the inner end of the rod e just inside of the standard D is a plate For lever extending at right angles and whose face is, preferably, formedor provided wit-h the suspending point for the heel end ofthe last, or

the rod e may extend through the plate and beV pointed for this purpose.

The outer end of the plate F is turned at right angles to its body orparallel with the axis or rod e', and is forked or slottedto receive athin plate G, one end of which has an extension or projection Il adaptedto enter a hole or recess in the top of the last, whereby said lastbecomes attached to and is rotatablev with the plate F when the -handwheel is turned. The plate G is adjustable in its slot by means of a setscrew g to suit different sizes of lasts.

The Standard D, which carries the devices for suspending the heelportion of the last, and the means for rotating said last, has its lowerend formed or provided withbearings or sleeves D D through one of whichD', the rod B passes, while the other sleeve D is internally threadedand is adapted to engage the coarse threads m of the other or screw rodC, the outerend of whichY carries a milled hand-wheel I which, whenoperated, rotatesI the screw rod and causes the` heel standard D to bemoved in or out to correspond with the size of the last to be inserted;

ICO

the said sleeve D' having a forwardly eX- tending pointer nsecured to itwith its point or free end lying in the path of the lines or marks onthe rod B indicating the size numbers of lasts.

On the rods B and C are mounted a series of arms .I placed side by sideand extending parallel with each other andtransversely of the machine;one of said arms being xedly secured to the fixed rod B, while the otherarms are adjustable toward and from each other by reason of the variablescrew threads upon the screw rod, as I shall presently disclose. Eacharm .I consists of two parallel members j connected by sleeves 7c and l,the former of which has a smooth interior which enables all of the armsexcept the xed one before noted to slide` freely along the rod B, whilethe other sleeves Z are internally threaded and adapted to engage thethreaded portions or sections of the screw rod C.

Fulcrumed between the members of the arms at points between the sleeves7c andZ are the levers L, the lower portions of which may be straightand the upper portions curved as shown, the said levers being each hungupon pins mounted in the membersjof the arms, and one member of each ofsaid arms being extended at one side and connected with oneend of aspring M the opposite end of which is in turn connected with the lowerfree end of the lever carried by the arm. This arrangement constitutes aseries of arms each of which is independently movable for a purposehereinafter described.

The upper ends of the levers are forked or v slotted and provided withlpins o upon which the measuring wheels or disks N are mounted to freelyturn, each wheel having its edge marked with inches and fractionsthereof starting from a zero point, and also may have said edge serratedor roughened `to increase the traction between the disks `and the lastwhich they are designed to engage, to cause a positive rotation of thedisks when the last is turned in contact with their edges.

On each arm upon one side of each disk is a face plate O having a stoplug fr and upon the opposite side is a pointer P adapted, in the normalposition of the disk, to register with the zero point.

In order that each disk may be returned to its initial or normalposition when rotated by contact with the last, I locate between eachface plate `and its companion disk a helical spring Q, one `end of whichis connected with the stationary face plate while the other end isconnected with the rotatable disk or its hub, whereby when the` disk isturned, as before stated, the spring is wound up, and when released thespring uncoils and returns each disk to its normal position, this returnof the disk being limited by the stop lugs on the face plates. i

In orderthat the entire series of levers with their disks or wheels maybe simultaneously thrown backward out of the path of the last to permitthe latter being placed in and removed from the machine, I mount betweenthe toe standard b and a standard p on the xed arm .I of the series, ashaft R which extends parallel with and above the rods B and C, and isprovided with a portion or plate S which serves asa cam and is adaptedto engage the levers whereby when the shaft is turned this cam portionor plate will contact with the levers and force them outward away fromthe last and hold them in this position by reason of the plate or camportion engaging the straight portion of the levers as shown by dottedlines in Fig. 2. When this cam por-` tion or plate is released fromcontact with the levers the springs M draw upon the lower ends of thelevers and move the disks to their normal position.

Machines of the character described and shown are useful for last-makersand dealers in this commodity, and are designed especially to prove thecorrectness of the lasts, and to permit any last to be reduced or builtup to a given size.

To determine if a last is of the proper size the same is placed in themachine upon the suspension points, and the heel portion secured to therotatable devices at that point, the levers and disks being first thrownbackward by the plate or cam previously described.

The last being of a given length the hand wheel I is rotated therebyadjusting the heel standard D until the pointer 'n registers with a likenumber on the graduated portion of the rod B; whichmovement also causesthe adjustable arms .I to be correspondingly moved toward or from eachother by reason of their engagement with the variable screw rod. The toepin or rod being now adjusted until its point engages the toe of thelast and secured, said last may be turned in transverse planes uponrotating the hand wheel E. The

last being thus secured the shaft R is turned to release the plate orcam S from its fixed contact with the levers, when the springs M drawthe levers inward until the disks contact with the last. Now as eachlever has a movementindependent of the others, it is apparent that thedisks will, conform tothe irregular outlines of the last at the pointswhere they engage, which I may sayrepresents the four measurementsbetween the toe and instep, with the pointers marking the zero points'onthe disks. Upon turning the hand wheel E the last is rotated and thefrictional contact between the last and disks is such that each disk isturned upon its axis until a complete revolution of the last is made.Owing to the irregular outline of the last each disk will be projectedout of line with the others so that the relative positions of thepointers may be instantly observed, and the measurements indicated `onthe combined IOO ISO

disks will disclose to the operator whether or not the last is ofstandard size.

If one or more of the disks should disclose the fact that the. last atsuch points is above or below the standard the deficiency is supplied byreducing the last by hand or building it up as the circumstances mayrequire, until the desired measurement is obtained. When the levers aremoved outward to throw the disks away from'the last, the springs Q arecoiled by the rotation of the disks and when releasedfrom the last, aspreviously described, these springs uncoil themselves and return thedisks to normal position with zero point and pointer aligned, and withthe pins w on the disks Ain contact with the stop lugs r on the faceplates. The last being accuratelymeasured it may be removed by releasingit from its heel and toe suspension devices, and a new last introduced.

0n the upper part of the heel standard D is a mark or groove 2, and' onthe plate or lever carried by the rotatable heel pin isa correspondingmark or pin 3, these marks being brought into engagement when the lastis to be rotated, and when they again coincide they indicate that thelast has made a complete revolution.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
